COUPLING FOR CONVEYERS OR RODS FOR PURPOSES OF UNDERGROUND CONDUITS.

SPECIFICATION forming part of Letters Patent N 0. 721,427, dated February 24, 1903. Application filed May 16, 1902. Serial No. 107,617. (No model.)

To otZZ whom it may concern:

Be it known that I, THOMAS J. COPE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented new and useful Im-. provements in Couplings for Conveyors or Rods for Purposes of Underground Conduits, of which the following is a specification.

My invention consists of a coupling for a conveyor or rod for use in underground conduits' and other purposes, the same embodying members, one of which is provided with a cross-head and neck, which may be seated in relative openings in the opposite members, admitting of the ready connection of said members and the easy disconnection of the same, as will be hereinafter described, the novel features of the same being pointed ou in the claims.

Figures 1 and 2 represent side elevations of a coupling embodying myinvention. Fig. 3 represents a longitudinal section thereof on line or; at, Fig.2. Fig. 4. represents an end view of the members separated. Fig. 5 represents a perspective view thereof.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A and B designate the members of a coupling consisting of heads A B, provided with sockets O C for the reception of the ends of the rods D. On the end of the head A are the ears E, between which and the adjacent socket C is the transverse passage F, said ears being separatedin their longitudinal direction, forming a channel G between them, the same being incommunication with said recess, forming together an opening of T shape.

On the inner ends of the earsE at the passage F are therecesses H, and on the head B is the longitudinally-extending neck J, at the outer end of which is the cross-head K, it being noticed that the neck J is adapted to enter the channel G, while the limbs of said cross-head are adapted to enter the recess H. At the inner end of the socket O is the shoulder L, the same when the members are coupled being contiguous to the outer end of the'ear E. 1

The operation is as follows: The members A and B are presented to each other and the cross-head. K introduced into the passage F,

the member B being somewhat in oblique position. The cross-head is then drawn into the recesses H, and the member B is lowered, whereby the neck J enters the channel G. Now as the cross-head K occupies a position in front of the ears E in the recesses H and the shoulder L occupies a position at the opposite end of said ears E it will be seen that the two members are firmlycoupled and connected and the conveyor may be advanced in the conduit, and the electric cable, wire, or other conductor attached thereto will follow saidconveyer without liability of the members A B to uncouple. As the conveyor is advanced other sections may be coupled to the preceding ones, and so the length of the conveyor may be extended as required. In order to assist the motions of the conveyor at the couplings, there is mounted in the head Bf theroller, wheel, or pulley M, which is adapted to run on the wall of the conduit, the efiect of which of construction without departing from the general spirit of my invention, and I do not desire, therefore, to be limited in each case to the same. 1

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a coupling member composed of an attaching-head, cars at one end of said head, a longitudinally-extendingchannel between said ears, recesses on the inner ends of said ears, and a transversely-extending passage on the head behind said ears, said passage being in communication with said channel and recesses.

2. A coupling for the purpose stated, consisting of opposite members, one of which comprises a neck, a T-head on the outer end thereof and means of attachment on the infor the purpose stated, a

mg an attaching-head, a neck on said head, to and a T-head on said neck, said attachinghead and T-head being adapted to engage opposite ends of said ears.
